TSCA New Chemicals Proposed SNURs Published

On June 10, 2015, at 80 FR 32879, the Environmental Protection Agency (EPA) proposed Toxic Substances Control Act (TSCA) significant new use rules (SNURs) for 30 chemical substances which were the subject of premanufacture notices (PMNs). This action would require persons who intend to manufacture (which includes import) or process these chemical substances for an activity that is designated as a significant new use by this rule to notify EPA at least 90 days before commencing that activity. The required notification would provide EPA with the opportunity to evaluate the intended use and, if necessary, to prohibit or limit that activity before it occurs.

In the Federal Register publication of October 27, 2014 (79 FR 63821) EPA issued direct final SNURs on these chemical substances. EPA subsequently received notices of intent to submit adverse comments on these SNURs. Therefore, as required by § 721.160(c)(3)(ii), EPA withdrew the direct final SNURs in the Federal Register of December 23, 2014 (79 FR 76900), and is now issuing this proposed rule on these 30 chemical substances.
